Method for allocating resources in wireless communication system supporting full duplex radio (FDR) technology, and apparatus therefor

Abstract

A method for allocating, by a base station, resources in a wireless communication system supporting a full duplex radio (FDR) technology, according to the present invention, may comprise the steps of: receiving, from a first terminal, a buffer status report (BSR) including an indicator which indicates the urgency of uplink data transmission; and determining, on the basis of the indicator, whether to allocate an uplink sub-frame for the first terminal in a situation where a downlink sub-frame is allocated to a second terminal during a specific time interval.

What is claimed is: 
     
       1. A method for allocating resources by a base station (BS) in a wireless communication system supporting a full duplex radio (FDR) scheme, the method comprising:
 receiving a buffer status report (BSR) including an indicator indicating uplink data transmission urgency from a first user equipment (UE); 
 determining to allocate an uplink subframe for the first UE based on the indicator in a state in which a downlink subframe is allocated to a second UE in a specific time interval; and 
 allocating the uplink subframe to the first UE in the specific time interval, based on the uplink data transmission urgency being equal to or higher than a predetermined threshold. 
 
     
     
       2. The method of  claim 1 , further comprising:
 receiving, from the second UE, a Quality of Service (QoS) level required by the second UE; and 
 allocating a downlink subframe for the second UE on a frequency band different from that of the downlink subframe allocated to the second UE in the specific time interval, wherein the QoS level is equal to or higher than a predetermined threshold. 
 
     
     
       3. The method of  claim 1 , further comprising:
 determining to allocate the uplink subframe to the first UE in the specific time interval based on both feedback information received from the second UE and the uplink data transmission urgency being lower than the predetermined threshold. 
 
     
     
       4. The method of  claim 3 , further comprising:
 allocating the uplink subframe to the first UE in the specific time interval, wherein the feedback information received from the second UE includes an indicator indicating acceptance of the allocation of the uplink subframe to the first UE in the specific time interval. 
 
     
     
       5. The method of  claim 3 , further comprising:
 allocating a resource different from the downlink subframe allocated to the second UE to the first UE, wherein the feedback information received from the second UE includes an indicator indicating rejection of the allocation of the uplink subframe to the first UE in the specific time interval. 
 
     
     
       6. The method of  claim 5 , wherein the different resource comprises a time resource or a frequency resource different from the downlink subframe allocated to the second UE. 
     
     
       7. The method of  claim 3 , further comprising:
 transmitting, to the first UE, a message instructing to hold off an uplink transmission during the specific time interval, wherein the feedback information received from the second UE includes an indicator indicating rejection of the allocation of the uplink subframe to the first UE in the specific time interval. 
 
     
     
       8. The method of  claim 1 , further comprising:
 receiving, from the second UE, a Quality of Service (QoS) level required by the second UE; and 
 allocating the uplink subframe to the first UE on a frequency band different from that of the downlink subframe allocated to the second UE in the specific time interval, wherein the QoS level is equal to or higher than a predetermined threshold. 
 
     
     
       9. A base station (BS) for allocating resources in a wireless communication system supporting a full duplex radio (FDR) scheme, the BS comprising:
 a transceiver coupled to a processor; and 
 the processor configured to: 
 receive a buffer status report (BSR) including an indicator indicating uplink data transmission urgency from a first user equipment (UE), 
 determine to allocate an uplink subframe for the first UE based on the indicator in a state in which a downlink subframe is allocated to a second UE in a specific time interval, and 
 allocate the uplink subframe to the first UE in the specific time interval, based on the uplink data transmission urgency being equal to or higher than a predetermined threshold. 
 
     
     
       10. The BS of  claim 9 , wherein the processor is further configured to:
 receive, from the second UE, a Quality of Service (QoS) level required by the second UE, and 
 allocate the uplink subframe to the first UE on a frequency band different from that of the downlink subframe allocated to the second UE in the specific time interval, wherein the QoS level is equal to or higher than a predetermined threshold. 
 
     
     
       11. The BS of  claim 9 , wherein the processor is further configured to:
 receive, from the second UE, a Quality of Service (QoS) level required by the second UE, and 
 allocate a downlink subframe for the second UE on a frequency band different from that of the downlink subframe allocated to the second UE in the specific time interval, wherein the QoS level is equal to or higher than a predetermined threshold. 
 
     
     
       12. The BS of  claim 9 , wherein the processor is configured to determine to allocate the uplink subframe to the first UE in the specific time interval based on both feedback information received from the second UE and the uplink data transmission urgency being lower than the predetermined threshold. 
     
     
       13. The BS of  claim 12 , wherein the processor is configured to allocate the uplink subframe to the first UE in the specific time interval, wherein the feedback information received from the second UE includes an indicator indicating acceptance of the allocation of the uplink subframe to the first UE in the specific time interval. 
     
     
       14. The BS of  claim 12 , wherein the processor is configured to allocate a resource different from the downlink subframe allocated to the second UE to the first UE, wherein the feedback information received from the second UE includes an indicator indicating rejection of the allocation of the uplink subframe to the first UE in the specific time interval. 
     
     
       15. The BS of  claim 12 , wherein the processor is configured to transmit, to the first UE, a message instructing to hold off an uplink transmission during the specific time interval, wherein the feedback information received from the second UE includes an indicator indicating rejection of the allocation of the uplink subframe to the first UE in the specific time interval.
